4.2.4Engineering Parameter Query

Engineering parameters can be queried in power-on or power-off status.
(1) Press and hold the ―MODE‖ and "SWING" button simultaneously for five seconds to enter the
engineering parameter query interface. The temperature area displays ―C00‖ and ―VIEW‖ is on.
(2) In "C00" status, continuously press the ―MODE‖ button for three times to enter engineering
parameter query.
(3) Select a parameter code by pressing ― ‖ or ― ‖.
(4) Press the ―SWING‖ button to return to the upper-level menu till quitting parameter query.
For the engineering parameter query list of the XK49 wired controller, refer to the engineering
parameter query list in XK46 engineering parameter query.
NOTICE! In parameter query, the function of "SWING" on the XK49 wired controller is equivalent to
the function of ―ENTER/CANCEL‖ on the XK46 wired controller.

4.2.5 Engineering Parameter Settings

Engineering parameters can be set in power-on or power-off status.
(1) Press and hold the ―MODE‖ and "SWING" button simultaneously for five seconds. The
temperature area displays ―C00‖. Continuously press the ―MODE‖ button for three times, and then press
and hold the ―MODE‖ button and "SWING" simultaneously for another five seconds to enter the wired
controller engineering parameter setting interface. The temperature area displays ―P00‖.
(2) Select a parameter code by pressing ― ‖ or ― ‖. Press the ―MODE‖ button to switch to
parameter value settings. The parameter value blinks. Adjust the parameter value by pressing ― ‖ or
― ‖ and then press the ―SWING‖ button to complete settings.
(3) Press the ―SWING‖ button to return to the upper-level menu till quitting parameter settings.
For the engineering parameter setting list of the XK49 wired controller, refer to the engineering
setting query list in XK46 engineering parameter settings.
NOTICE! In parameter settings, the function of "SWING" on the XK49 wired controller is equivalent
to the function of ―ENTER/CANCEL‖ on the XK46 wired controller.
